"You are what you eat". Consuming a well-balanced diet is key to a healthy life, but at times we simply ignore it. Keeping our kidneys healthy is vital for our overall health. Fortunately, a healthy diet can help keep the kidneys in good shape. Here’s how:

Choose or prepare food with less salt or sodium: Avoid overly processed foods and stick with natural foods. Don’t consume an excessive amount of salty foods. Keeping a check on the sodium intake will keep your blood pressure levels safe and not lead to any complications with the kidney

Eat the right amount of proteins: Consuming high amount of proteins can stress the kidneys. However, if you don’t get enough you can become weak. So, it is essential to calculate how much protein your body needs and limit your protein intake accordingly. Be aware of which foods contain high protein including meat, poultry, and seafood and incorporate them into your diet wisely.

Fluids: Drinking more water is not always good. The National Kidney Foundation (NKF) recommends drinking just enough fluids to keep your urine either light yellow or colorless. A standard recommendation is 13 cups daily for men and 9 for women. Also, cranberry juice has a positive association with kidney health for a long time, especially urinary tract infections and can be consumed.

Watch your Potassium and Phosphorous: A diet high in potassium and phosphorous can thwart the kidney function. A diet with the right amount of Potassium will help your nerves and muscles work the right way. Also, the right phosphorous levels will help protect your bones and blood vessels. It is better to stay away from packaged foods, junk foods and colas that contain high phosphorous and potassium.

Restrict the Fructose: As with sodium, your sugar levels are also to be watched. Since a high sugar diet can lead to diabetes and increase your risk for kidney disease, avoid high sugar foods. Sweetened beverages like sodas, fruit juices and energy drinks are not recommended.

Kidney-friendly Superfoods: Adding the following foods to your diet can help promote optimal kidney function:

Colon polyps are growths that are typically found in the large intestine. Although the causes behind the occurrence of colon polyps are not known, this condition is usually seen to affect adults.

These colon polyps might turn into colon cancer over a period of time; the development of cancer can happen over a number of years.

Colon polyps are usually symptomless; hence it becomes difficult to diagnose the condition. They are commonly found as additional results of screening tests for colon cancers. Screening tests are conducted when there is a suspicion of a disease but it displays no significant symptoms. The symptoms can only be visible if the polyps are enlarged.

As the presence of most polyps becomes evident only during colon cancer tests, it is recommended that regular tests for colon cancer be conducted for adults over the age of 50.

Some of these tests include:

Colonoscopy: This is highly recommended for detecting colon polyps. A small tube used for viewing is inserted into the colon by the doctor.

Flexible Sigmoidoscopy: This test is similar to colonoscopy but only a part of colon i.e sigmoid colon is screened.

Computed Tomographic Colonography (CTC): Also known as virtual colonoscopy, various computer systems and X-rays are used to create a detailed picture of the colon so that the doctor can search for polyps.

The size of the colon polyps helps to identify if the polyp is cancerous or not. Chances of the polyp being cancerous are high if the size of the polyp is higher than 1 cm or 0.4 inches. Hyperplastic polyps (smaller polyps) do not become cancerous and hence, do not need to undergo a colonoscopy. Another form of polyp is the sessile polyp which is usually a flat growth without a stalk and grows on the inner wall of the colon. Similar to other polyps, these polyps can be found and removed using a colonoscopy or a sigmoidoscopy.
